Maintenance Guidelines
  • Regular Inspections:
    Periodically inspect the unit during operation. Monitor system pressure and pump performance for abnormal noises or irregularities. If any issues arise, stop the machine immediately and contact technical support.
  • Routine Cleaning:
    After prolonged use, regularly inspect and clean the filter elements (every year). Remove and check the elements for any signs of damage or deformation. Clean them using appropriate cleaning agents or a high-pressure water jet. Wipe the exterior of the unit with a damp cloth to remove dust and debris. Regular cleaning helps maintain optimal performance and extends service life.
  • Seal Integrity:
    Regularly check for leaks to ensure proper sealing of the system. If any leakage is detected, address it promptly to avoid compromising the filtration efficiency and operation.
  • Replace Wear Parts:
    Based on usage conditions, replace consumables such as O-rings and filter elements regularly to maintain optimal system performance.
  • Scheduled Maintenance:
    Conduct comprehensive inspections at regular intervals. This includes checking the electrical system, filtration system, and tightening all mechanical components. Any abnormalities should be resolved immediately.
Long-Term Storage & Care

  • Thorough Cleaning:
    Before long-term shutdown, perform a complete system cleaning. This includes backwashing, cleaning the filter elements, and flushing the internal components to ensure no debris or contaminants remain.

    Drying Process:
    After cleaning, open all drainage and vent ports to allow for adequate ventilation and drying. This prevents rust and corrosion caused by moisture. If necessary, use drying equipment to accelerate the process.

    Protective Measures:
    Cover key components like the motor and control panel with dust covers to protect against dust and moisture. Close all valves to prevent foreign objects from entering the system.

    Regular Inspections During Downtime:
    While the unit is not in use, inspect it at least once a month. Check for signs of moisture damage or rust. If any issues are found, address them promptly to ensure the system is ready for reactivation.

Troubleshooting
    1. System Fails to Start:
      Possible causes: incorrect operation, low diatomaceous earth level, electrical component failure.
      Solutions:Reset the system and restart in automatic mode; refill diatomaceous earth in the dosing tank; manually test and inspect electrical components—repair or replace any faulty parts.
    2. Poor Filtration Performance:
      Possible causes: insufficient diatomaceous earth, uneven coating, damaged filter elements.
      Solutions:Adjust the diatomaceous earth dosage; ensure consistent coating and normal operating pressure; inspect and replace damaged filter elements if necessary.
    3. High Pressure Differential & Frequent Backwashing:
      Possible causes: clogged filter elements, incompatible diatomaceous earth type.
      Solutions:Clean filter elements using chemical soaking or high-pressure washing; ensure the diatomaceous earth used matches the filter specifications.
    4. Equipment Leakage:
      Check leak location.If at pipe connections: gasket may be damaged or bolts loose. Replace gasket and tighten bolts.If on the unit body: sealing bolts may be loose. Tighten bolts or replace the seals.
    1. Abnormal Motor Noise:
      Possible causes: worn bearings, loose installation, or foreign matter inside motor.
      Solutions:Inspect motor bearings—lubricate or replace them; secure the motor; remove any debris from the motor housing.
    2. Dosing Tank Clogging or Leakage:
      Possible causes: malfunctioning dosing and feed valves, sedimentation of diatomaceous earth.
      Solutions:Manually test the dosing and feed valves. Repair or replace any malfunctioning valves; remove sediment from the tank; clean filter elements to increase suction or extend coating time.

Chlorinator

Will the water taste salty?
  • Generally you should not be able to taste any salt in the pool because the level of salt in the water is so low, however some people with sensitive palates might detect a small amount of salt. 
Why use electronic chlorination over traditional chlorine?
  • Traditional chlorine ties up with wastes in the water creating what are called chloramines. Electronic chlorinators continuously oxidize the chloramines and create "Free Chlorine". Chloramines are what cause common side affects associated with chlorine such as irritation to eyes and skin, bleaching of bathing suits, and that awful chlorine smell. Furthermore you will no longer have to buy, mix or store chlorine, which saves time, money and keeps you from direct contact with a potentially harmful chemical. 
What kind of maintenance do I have to do with this system?
  • Continue to test the chlorine level of the pool on a weekly basis. Adjust the dial of the FULLVISIONchlorinator to adjust more or less chlorine. If there has been a large number of swimmers in the pool or the pool water is cloudy, you can put the FULLVISION chlorinator into "Super Chlorinate" mode where it will automaticially generate the maximum amount of chlorine for 24 hours. The Turbo Cell should be inspected and cleaned if necessary every three months or when starting up the system. 

Pool Pumps

Why is my pump running hot and powering off?
  • This maybe caused by insufficient power due to an undersized wire or a poor connection.  Check your owner’s manual for proper wiring.
  • Your local power company might be experiencing a power drop especially during a heat wave.  Restart your pump when the weather cools to confirm that the problem is really in the motor.
  • Your pump has a thermal overload, which will shut the motor off when it gets too hot—it will restart once it has cooled down.  Check the air intake vents of your motor to ensure they are free of debris.  If debris is blocking these vents, it will cause the motor to run hot and possibly shut down.
  • Make sure your pump is located in an area with adequate drainage.  Flooding from rain and other sources could cause a pump to run hot and cut off.
Why is my pump noisy?
  • The motor has an internal cooling fan that can be heard. When installing your pump, it is advised to carefully consider the location; under a bedroom window may not be an ideal location.
  • Vibration from the pump’s feet and the base (where the pump rests) can cause the pump to be noisy.  A piece of old carpet or rubber between the pump’s base and the equipmentpad might reduce the noise.
  • Ensure the pump is level and the suction lines are not higher then the pump.
  • The bearing(s) might be noisy due to age or high concentrations of chemicals and heat. A leaky pump seal could damage the front motor bearing.  It is very important to quickly repair any leaks around the pump to prevent extensive damage.  It is recommended that you replace the bearings or the entire motor.
  • Contact an Authorized FULLVISION Dealer for repair.
  • Many times a noisy pump can come from cavitation. Cavitation has two possible causes, which are both hydraulically (water flow) related.  The first is that the suction piping is undersized.  If this pipe is undersized, the amount of water the pump requires to operate properly is reduced.  Increasing the pipe size (increasingwater flow) or reducing the size of the impeller (decreasing water flow) can quiet the pump. The second is that there is little or no backpressure on the pressure side of the system (water feature pumps are a good example).  Adding a valve or something to increase backpressure is advised.
Why is my pump cutting off and on every 5-10 seconds?
  • FULLVISIONmotors are factory wired for 240 volts unless the motor is 120 volts ONLY. Check the voltage of the incoming supply power and ensure the motor is wired or can be wired for this voltage (data plate on motor will help provide voltage and wiring information).  Also check for loose or badly connected wires.  Contact a certified electrician for repair.
Why are there air bubbles flowing into the pool from the return fitting(s)?
  • If air is returning into the pool there might be a leak on the suction side of the pump.  Check the following items that maybe causing air to enter the system:  It may be necessary to contact an authorized FULLVISIONdealer for repair.
  • The strainer cover and O-ring.  Tighten if loose or replace gasket if damaged.
  • Level of water in the pool is low causing water and air to mix into the skimmer..
  • The skimmer weir may be stuck in the up position causing water and air to mix in the skimmer.
  • Check the drain plugs on the pump strainer housing.
  • Check all of the threaded fittings for leaks from improper sealants or sealing procedures.
  • Check glued fittings for bad glue joints.
  • Check all valves for possible leaks. Valve stem O-rings are a common suction leak point.
  • Check and ensure the pump is not cavitating.
  • Check pump housing for cracks.
Why won’t my pump fill with water (prime)?
  • An air leak on the suction side of the pump.
  • Check to make sure the suction line is free of obstructions.
  • Check to make sure the impeller is still attached to the shaft of the motor.  If the impeller has broken off, it will need to be replaced.
  • If the pump is installed a distance from the pool or is elevated above the normal deck level, the time needed to prime the pump could be longer. For elevated installations, a check valve may be needed on the suction line to allow for easier priming.
What should I use as a lubricant for my o-rings and gaskets?
  • FULLVISIONrecommends a silicone or Teflon based lubricant for all o-rings and gaskets. Jack’s 327, by FULLVISION, is the best for the job. Other lubricants may cause premature failure and swelling of the o-rings and gaskets. NEVER USE PETROLEUM JELLY for a lubricant. Its’ oils will break down the rubber of the gasket or o-ring.
Can I replace my motor with a lower horsepower motor?

Horsepower is matched with the impeller inside the pump. Having a larger impeller on a smaller horsepower motor will cause premature failure of the motor. It is better to replace it with the same horsepower.

Do I need to keep grass, shrubs, and vegetation away from my motor?
  • Always keep the pool equipment clear and ensure that there is nothing growing over the motor. If insects are a large problem in your area, treat for insects. The air circulation around the motor is crucial for proper operation. Failure to ensure proper air circulation will reduce the life of the equipment.
Can I run my pump without water?

FULLVISION Pool pumps should never operate without water. The pump seal assembly in the pump volute (The area between the strainer basket and the pump motor) protects the pump motor from pool water. This seal assembly gets hot and is cooled by the pool water. If the pump is running without water, the seal will overheat and melt, If left running without water for a long period of time, the heat generated could damage the PVC pipe and other system components.

How does my in-ground Pump operate?
  • FULLVISIONin-ground pumps are self-priming centrifugal pumps.These pumps have a vacuum chamber, commonly known as a pump housing. 
    The pump housing must be filled with water in order to create a vacuum, resulting in the pump drawing the water out of your pool or spa. The pump housing will remain full of water while the pump is on, and will remain full or partially full when the pump is shut off.
  • When powered on, the motor will begin to rotate.  2-speed pumps will power on a pre-selected speed or with some controllers, it will cycle at high before changing to the lower speed.
  • The motor spins the pump impeller, located inside the pump volute. While the motor is rotating, the tips of the impeller are hydraulically sealed inside the pump diffuser, which is responsible for self-priming.
  • Self-priming can only occur if the pump has a diffuser—all inground FULLVISIONpumps have an internal diffuser.  It helps to eliminate any air approaching into the pump housing from the suction piping.  As all the air is removed from the system, you will notice bubbles returning to the pool through the return fittings.  A full prime occurs when the bubbles stop returning to the pool and the pump basket is full of water.  The filter pressure will rise as the pump reaches full prime.  The actual gallons per minute (GPM) vary with the type of pump, horsepower, pipe size, distance from pool and other restrictions within the plumbing system.
  • FULLVISIONself-priming pumps are very dependable and simple in design.  They require a sufficient supply of water from the pool or spa, and no air in the suction lines.  Air could come from a loose strainer cover, a leak in any valve, a pinhole in any suction line or a crack or loose connections in the underground piping.

Pool Cleaners

Pressure cleaner moves slowly or not at all.
  • Low pressure. Use pressure-testing fitting to check the pressure. It should be approximately 27psi.

  • Hose length is incorrect.  Adjust hose to required length using the measuring tape included with the cleaner. 
  • In Pools with a steep slope, it is better to use a cam with the next lower number of prongs (less frequent Spin-Outs) in order to allow for longer straight runs of the cleaner. 
Why doesn't my cleaner move?
  • FULLVISIONsuction cleaners depend on several factors to operate. First, there must be enough water flow past the “turbine”. Use the “vacuum gauge adaptor” or “flow gauge” supplied with the cleaner to measure the vacuum in the cleaner hose. You should have 1" vacuum per section of hose. If you happen to have the new “flow gauge” adjust the flow so the reading is at least ½ way between maximum and minimum.  Follow the directions in the FULLVISION owners guide or video.
  • The 4 small "shoes" connected to the pods must be able to grip the pool surface. Make sure that the "shoes" are not worn out and that the surface of the pool is not slippery because of an algae buildup.  Also make sure you have the correct “shoes” for the surface of your pool. The right shoes are standard/slotted for plaster and Pebble-Tec; cork for vinyl and fiberglass; and ceramic for tile.
  • There is an obstruction in the cleaner. Remove the consumer inspection plate at the bottom of the cleaner (one self contained screw needs to be loosened) and see if a rock, twig or large piece of debris has stuck between the bearings and turbine. Shake the head of the cleaner to dislodge any internal debris.
  • The turbine, a-frame and "pods" must be working correctly. Any wear in the "drive train" can cause problems. To check for wear hold the left and right "pods" in your hands and firmly try to rock the “pods”. All force on the  “pods” should be transferred to the “turbine” and no play should be evident in the pods. If there is more than ¼” of play, parts need replacement. Contact your FULLVISIONAuthorized dealer for repair.

Light

What is the difference between a niche and a light?
  • A niche is a housing that is permanently mounted in the pool wall, while the light is a “fixture” that is secured into the niche. 
What is the difference between 12V and 120V?
  • A 12V light receives its power from a transformer, which steps down 120V to 12 V.  120V is your standard house voltage. Some areas of the country do not allow 120V lights. The brightness is equal for either voltage because brightness is measured by the bulbs wattage. 
My light is not working?
  • Check the power supply; verify that the breaker in the breaker box and the light switch are in the on position, if all is okay, the bulb maybe blown. 
How do I change my bulb?
  • ALL POWER TO THE LIGHT MUST BE OFF.  This includes the circuit breaker and the light switch. Once the power is verified to be off, unscrew the light fixture from the niche. There should be a single mounting screw in the 12 o’clock position; loosen the screw and lift the light onto the pool deck. (When the light was first installed, the installer should have left excess cord).   Depending on the age of the light, there may be a clamp or a back securing ring with nuts holding the light onto the lens. Expose the bulb, unscrew and install the new bulb. 
  • NOTE: When replacing a bulb, you should replace the lens gasket, as a precaution. If you replace the bulb and the light continues not to work, your gasket might be bad. Lubricate the new lens gasket, resecure the lens and faceplate and secure into the niche. 
  • FULLVISIONrecommends you consult a licensed electrician for any electrical work.
